strange codes shown in the website URL [closed]

Question

When one uses Chrome to visit my site’s homepage. There is a strange series of codes shown immediately after the URL domain name. I have not set anything about the default homepage of the website, so I don’t know why it appears and what function is it.

like this: "HTTP://www.websitename.com/?bwnutm=r3swa2"

what is this "?bwnutm=r3swa2" for?
